While Tadalista (Tadalafil) is primarily used to treat erectile dysfunction (ED) and sometimes benign prostatic hyperplasia (BPH), it can cause side effects in some individuals. Mood swings are not among the most common side effects of Tadalista, but they can occur in some people due to the medication's effects on the body, including:

Psychological effects: Some users may experience anxiety, stress, or emotional changes due to concerns about their sexual performance, which could lead to mood fluctuations.

Other side effects: More common side effects of Tadalista include headaches, dizziness, or fatigue, which could indirectly affect mood. If you're feeling unwell, it might affect your emotional state.

Hormonal or blood flow effects: Tadalista works by improving blood flow, which can have various effects on the body, including on hormones or neurotransmitters that influence mood.

If you notice significant mood swings or emotional changes while using Tadalista, it’s a good idea to talk to your doctor. They can help determine if the medication is the cause or if there might be other underlying factors.
